Destiny's child singer sounds off on Twitter

Michelle Williams is not having it, y'all. Beyoncé's former Destiny's Child group-mate is hitting back at an inappropriate fan who scolded her for a lack of public congrats over her BFF's baby news.

The internet is full of anonymous jerks -- a phenomenon Michelle Williams experienced for herself today.

Just a days after news broke that Williams' Destiny's Child group-mate Beyoncé gave birth to a baby girl, a particularly ardent fan took the singer to task for not issuing a public congratulations to her BFF on Twitter.

"Let's get ONE thing straight," Williams replied. "I do NOT have to say congrats to someone when they're NOT on twitter… ESPECIALLY when I talk or email them all the time… or when I'll be physically present as well… so harassing and stalking my timeline to see if I've mentioned something is POINTLESS!!!"

"My friendship with people aren't always for twitter display. Respect that and get a LIFE!!! Enjoy this FINE day!!! God bless!!!!"
